Sports medicine is focused on assisting people to improve their athletic performances, recover from injury as fast as possible.




About 55% of all sports injuries are knee injuries. Knee injuries also make up 25% of problems treated by orthopedic surgeons. Knee injuries or Patellofemoral syndrome is caused by the kneecap repeatedly moving against the leg bone. This movement damages the kneecap’s tissues and causes pain. Basketball, cycling, swimming, football, volleyball, and running are the most common sports where these injuries occur.



Around 7% of all sports injuries are elbow injuries. Also called epicondylitis, tennis elbow is caused by a repetitive use of the elbow. This repetition creates tiny tears in the elbow’s ligaments. Pain can be experienced on the inside or outside of the elbow, but the outside is the most common.



The ACL or anterior cruciate ligament connects the leg bone to the knee. The act of suddenly stopping and changing directions or a hard impact to the side of the knee can cause a strain or tear of the ACL. These are one of the most severe sports injuries, but not the most common. A completely torn ligament requires surgery and may cut an athletic career short. If you think you might have an ACL injury, see your doctor immediately.



A strain is a muscle or tendon injury. There are three muscles behind the knee that make up the hamstring. They are most often “pulled” when an athlete is overusing or overstretching the muscle. The pain is caused by tears in the muscles or tendons. Sometimes bruising can occur in pulled hamstrings. Activities like hurdling or falling forward while waterskiing are all common causes of a hamstring strain.

Hamstrings take a very, very long time to heal. Often between 6 and 12 months because walking causes a lot of stress to an injured hamstring. Gentle stretches can greatly help hamstring strains, as well as resting, ice and anti-inflammatory drugs.



Shin Splints are known for shooting pain down the front of the leg. While it happens most often to runners, shin splints can also occur in people who aren’t used to exercising or who have increased their exercise intensity too quickly. Sometimes shin splints can be a result of a stress fracture in the bone. If resting doesn’t help the pain go away, it’s important to see your doctor and make sure you don’t have a stress fracture. Minor shin splints can be improved with ice, rest and over-the-counter pain medication. Wearing proper shoes, stretching and knowing your limits can help prevent shin splints.



Shoulder injuries, including dislocations, sprains and strains, make up 20% of all sports injuries. Shoulder injuries are caused by overuse. Sports that require overhead movement, like tennis, swimming, weightlifting, baseball, basketball and volleyball, are the most common culprits. Shoulder injuries should be treated with rest, ice, and anti-inflammatory medication. You can prevent shoulder injuries by doing strength-building exercises in the off-season.



Branch of translational research in tissue engineering and molecular biology which deals with the “process of replacing, engineering or regenerating human cells, tissues or organs to restore or establish normal function.

Amniotic Growth Factors

Extracellular matrix composition of Collagens I, III, IV, V, VII, and other structural proteins provides a natural scaffold to facilitate cellular adhesion while assisting cellular migration and proliferation.

Adipose Cells

Adipose tissue-derived cells have the capacity for self-renewal and multipotential differentiation. This allows them to become many different cell types. Adipose tissue-derived cells, play a key role in reconstructive or regenerative medicine as they have been effective in developing new orthopaedic treatments.


Platelet-Rich Plasma (PRP) Injections

Injections that can use the blood from the patient by separating platelets in a centrifuge. Then the platelets can be re-injected into the injured area, releasing growth factors that promote healing tissue naturally.
